VOLTAIC BATTERY.

SPECIFICATION forming part of Letters Patent No. 246,942, dated September 13, 188].

' Application sied February 1e, 1881.. (No model.)

To all whom it may concern:

Be it known that I, JosnrHUs G. CHAMBERs, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvementin Curative Voltaic Batteries, of which the following is a specication.

My invention relates to an improved construction of those voltaicpiles or batteries which are adapted to be worn or suspended vupon the 1o person for remedial purposes.

My im proved curative battery comprises one or more systems or couples, of which each system is composed oftwo metallic disks ofstrongly-contrasted polarity-as, for exam ple, of zinc and copper, respectively-with customary in terposed diaphragm of bibulous paper, felt, or cloth for reception and retention of the acid or other excitant. These couples are contained in a shallow cup, whose walls areformed of vul- 2o canite or other electrical nouconductor, and whose bottom is composed of a disk of copper, having peripheral claws which inclasp the walls of the cup and extend slightly' over its top. Pivoted to the top of the cup are buttons of Zinc.

When applied to the person with the top surface of the battery next to the wearer, his skin, with its normal saline secretions, completes the circuit and becomes the theater ofthe wellgo known galvanic action.

Inthe accompanying drawings, Figure lrepresents my battery, viewed on its face or top side. Fig. 2 represents the same viewed onits bottom or rear side. Fig. 3 is an axial section on the line x x. Fig. 4 represents my cup divested of its disks. Fig. 5 shows a series of disks of three voltaic couples. Fig. 6 representsaseries of my batteries attached toabclt.

A represents an annular disk of vulcanite,

4o gutta-percha, glass, or other firm and electricallynon-conducting material. aare orifices in the same, to enable the insertion of a cord, B, or a ring or other means of suspension upon the person.

' .i 5 C is a copper plate, which closes the central orifice of annulusAon its rea-r side,and Whose radially-projecting claws c embrace the said annulus around its periphery and face, in the manner shown in Figs. l, 2, 3, and 4. The said 5o annulusAand said disk or shell C thus united constitute lthe inclosing-cup of my battery. Pivoted to face of annulus A are buttons Z, of zinc.

l 2 3 are three voltaic couples or systems, of which each system comprises three disks, z do, of zinc, cloth, and copper, respectively, of size adapted to loosely occupy the central orifice of my cup A C. Of these disks all the metal ones except thebottom one are preferably perforated at their centers, as shown in Fig. 5, for the free 6o passage of the acidulated water or other excitant.

In the form of my invention here selected for illustration the imperforate Zinc disk shown at the extreme lel't of Fig. 5 is first inserted, 65 then a diaphragm of moistened cloth, followed by a copper disk, these three pieces composing one system or couple, after which the other couples are inserted in like order, and are secured by the closure over them of the buttons 7o Z. The apparatus is now ready for use.

Should the galvanic action become impaired by the drying up or the neutralization of the acid, it can be restored atany moment by pouringin additional acid through the central orices or by taking the disks out and remoistening the diaphragms. Whichever of these modes be adopted, care must be taken that while applying sufficient acid for saturation of the diaphragms such excess is avoided as 8o would moisten the contiguous metallic surfaces of the consecutive couples, and -thus generate cou n ter-curren ts.

Whenever the metallic surfaces have become too much impaired by oxidation, the battery is taken apart and the surfaces cleaned. At the same time the diaphragms may be renewed, if necessary.

It' the galvanic action is found to be too strong, it may be moderated by turning one or 9o more of the buttons Z out of contact with the last copper disk, c, as indicated by dotted lines in Fig. 1.

The above-described embodiment of my in' vention is manifestly susceptible of various Inodications. For example, the plate C may be made a member of the rst couple by the interposition of a diaphragm between it and the first zinc disk, which, in that case, may be perforated like the others. Such arrangement zoe A and metallic shell C c', constituting a cup o1' receptacle, within which one or more voltaic couples are inelosed by means of buttons Z,

substantially as set forth. c5

In testimony of which invention I hereunto set my hand.
